Stormsaver Active Attenuation

Active Attenuation crates and rainwater harvestingThe Stormsaver Active Attenuation brings together Attenuation and Rainwater Harvesting thanks to Stormharvester weather prediction technology. The system counts towards 100% of attenuation volumes on-site at the same time as harvesting and re-using rainwater for a range of applications.

Flood prevention infrastructure, comprising tanks or crates, are now installed into all new commercial developments. These structures capture rainfall run-off and slowly release it at an allowed rate, to the storm drain system, but unbelievably they sit empty for over 95% of the time waiting for rain.

By separating the attenuation structures into two separate tanks and installing our technology into the clean roof run-off, Stormsaver enables previously wasted storage capacity within these tanks to be used for rainwater harvesting in a way that has never been possible before. The storage can be provided using crates, tunnels or large single-piece GRP tanks and our solution can use any of these.


So how does it work?

Active Attenuation tanks and rainwater harvesting

Half of the attenuation tanks take run-off from the carparks and act just as a regular attenuation tank draining down following heavy rainfall.

Working in partnership with the Stormharvester team, we combine our products with their technology which is linked directly to a highly accurate short to medium term Met Office Rain Prediction system.

When rainfall is predicted, Stormharvester's telemetry recognises the anticipated rainfall event. A control system lowers the water in the attenuation tank to a safe level, so when the rain arrives all the necessary attenuation capacity is available within the tank.

The system has a built-in failsafe system so that there is no risk of flooding even in the unlikely event of a system failure.

Utilising mandatory flood protection infrastructure in this way the Stormsaver solution provides all new commercial buildings with a source of valuable re-cycled rainwater without the need for additional expensive infrastructure. The system reduces installation costs and reliance on main water supplies at the same time as maintaining necessary attenuation capacity.

Suddenly, your unused attenuation tank is working for you; creating revenue, reducing running costs and making you more sustainable and environmentally friendly.


The Benefits of Active Attenuation

  • Reduce Construction costs
  • Reduce paybacks for Rainwater Harvesting
  • Additional BREEAM points (3 points)
  • Reduce foot print for sites with Rainwater Harvesting and Attenuation
  • 100% of the cost of the rainwater harvesting can be offset against tax under the ECA scheme
  • Reduces discharge rates in storm events
  • Reduces demand on public water supply
  • Saves money on water bills
  • Assists with stormwater and flood control.

Excellent Job!!!"

Testimonial - Mechanical and Engineering Contractor

“Stormsaver has helped us to upgrade the existing rainwater harvesting system. We desperately needed support and within one month they had attended site, carried out a survey, manufactured the new control panel, and installed and commissioned the system. Together the team at Stormsaver responded quickly, understood our requirements, and worked to ensure that we had the best solution. Their knowledge and expertise have resulted in us now having a fully functional, efficient rainwater harvesting system and we would highly recommend that other clients who need their existing rainwater system upgrading, contact Stormsaver for support.”

“What an absolute credit to our team your engineer was. I was most impressed with the way he worked and couldn’t have asked for a better or more helpful commissioning engineer. I will certainly be recommending Stormsaver to my colleagues”
